Unreal Speech is a production-ready text-to-speech API built on the open-source Kokoro TTS engine. It gives developers and businesses natural speech synthesis at a fraction of the cost of ElevenLabs, Amazon Polly, Google Cloud, and Microsoft Azure. The API streams audio in about 300 milliseconds and supports long-form jobs up to 10 hours per request.

Kokoro runs on an 82-million-parameter decoder-only model that blends ideas from StyleTTS 2 and iSTFTNet. You get 48 voices across eight languages, including US and UK English, Mandarin, Hindi, Spanish, Portuguese, Japanese, French, and Italian. Per-word timestamps let apps highlight text in sync with playback, which helps with accessibility, karaoke-style UIs, and interactive readers.

The REST API exposes four endpoints: /stream for sub-second synthesis of up to 1,000 characters, /speech for up to 3,000 characters with timestamp URLs, /synthesisTasks for async jobs up to 500,000 characters, and a websocket /streamWithTimestamps route for live audio plus word timing. SDKs ship for Python, Node.js, and React Native, with sample code on the homepage.

Kokoro TTS Studio on unrealspeech.com offers a free browser demo to test voices before signing up. Paid plans remove attribution requirements for commercial audio. Enterprise customers on the platform process billions of characters monthly with 99.9% uptime.
